A wrapper for the ChatNVIDIA class that provides default configuration
|
|
and could be extended with additional methods if needed.
|
|
|
|
Note: This class uses __new__ instead of __init__ because langchain_nvidia_ai_endpoints
|
|
is an optional dependency. We cannot inherit from ChatNVIDIA at class definition time
|
|
since the module may not be installed. The __new__ method allows us to lazily import
|
|
and return a ChatNVIDIA instance only when Nvidia() is instantiated.

Args:
|
|
llm_config (dict): Configuration parameters for the language model.
